PFLAUMER BROTHERS: Hardner

TERAMINE 626 from Pflaumer Brothers is a modified aliphatic amine hardener engineered for formulators developing fast-setting epoxy adhesives, repair mortars, patching compounds, and related construction and industrial repair materials. Featuring a nonyl phenol-free and benzyl alcohol-free formulation, the hardner delivers rapid cure, excellent adhesion, and dependable performance while supporting the industry's growing demand for safer, high-performance epoxy technologies.
Whether repairing damaged concrete, installing flooring systems, or bonding structural components, contractors need epoxy systems that develop strength quickly without compromising long-term durability. TERAMINE 626 was developed to meet these demands by providing exceptionally rapid setting and curing characteristics while maintaining excellent adhesion, flexibility, and moisture resistance.
Compatible with conventional liquid epoxy resins, the hardner can be formulated at a convenient 1:1 mix ratio, simplifying dispensing and field application. Its modified aliphatic amine chemistry produces low-modulus systems with good flexibility, allowing cured adhesives and repair materials to better absorb movement and stress while maintaining strong bonds. The absence of both nonyl phenol and benzyl alcohol provides formulators with an alternative chemistry aligned with evolving environmental and workplace safety objectives.
The product is designed for use as an accelerant with amine-based hardeners in epoxy adhesives, patching compounds, and decorative applications such as decoupage. It is also well suited for repair mortars, trowelable flooring systems, and other rapid-repair applications where fast strength development helps reduce downtime and return surfaces to service more quickly. Its excellent adhesion and moisture resistance further enhance long-term performance in demanding industrial and commercial environments.
TERAMINE 626 is recommended for use at 95 phr with standard bisphenol A epoxy resins and is intended for professional and industrial applications. Pflaumer recommends laboratory and field testing to optimize formulations for specific end-use requirements. The company's technical service team is available to assist customers with formulation development and application guidance.
